“…The ramets are connected by rhizomes that form colonies and consist of nodes, two aerial folioles responsible for photosynthesis, and submerged, nely divided folioles with a root function responsible for water and nutrient absorption (Room 1983;Sculthorpe 1967). In the submerged folioles of S. auriculata, the Desmonostoc strain ( UFLA 12) was observed and subsequently isolated (see in Pimenta et al 2022). Desmonostoc (UFLA 12) strains have terminal and intercalary heterocysts, can perform BNF, and form long laments surrounded by a diffusible mucilaginous sheath.…”

“…The cyanobacterial strains used in this study, Desmonostoc (UFLA 12) and Cronbergia (UFLA 35), were previously isolated from the epiphyton of S. auriculata roots (Pimenta et al 2022)d stratiotes (M. Biondi, UFLA, Brazil, unpublished research), respectively. Both cultures are deposited in the Collection of Cyanobacteria Cultures (CFC -UFLA), available at the Federal University of Lavras (UFLA).…”

“…Cyanobacteria have the ability to form endophytic associations with various organisms, including plants (mosses, cycads, ferns), fungi (forming lichens), and algae (Adams 2000;Aguiar et al 2008;Rai et al 2002). In addition, several strains form epiphytic associations with oating aquatic plants, such as S. auriculata (Pimenta et al 2022), and some even with submerged aquatic plants, such as Stratiotes aloides, showing allelopathic activity (Mohamed and Shehri 2010).…”

Clonal plants, like cyanobacteria, are widespread and perform important ecosystem functions, influencing the structure and composition of the habitats in which they occur. Some cyanobacteria perform biological nitrogen fixation (BNF) and can affect plant growth as nitrogen (N) is a limiting nutrient. Therefore, to investigate whether heterocystous cyanobacteria favour individual growth and reproductive strategies (sexual reproduction and clonal growth) of Salvinia auriculata, we carried out a greenhouse experiment with the inoculation of two strains of cyanobacteria, Desmonostoc (UFLA 12) and Cronbergia (UFLA 35). S. auriculata ramets were grown in plastic pots with the following treatments: (D) Desmonostoc (UFLA 12) inoculum; (C) Cronbergia (UFLA 35) inoculum; (D + C) Cronbergia (UFLA 35) + Desmonostoc (UFLA 12) inoculum, and (Co) control, absence of cyanobacteria. Treatments (D) and (D + C) positively influenced the clonal growth of S. auriculata. Desmonostoc inoculation contributed to numerical increase in shoots, biomass gain, and shoot size. Cronbergia (UFLA 35) alone was not able to promote the growth of S. auriculata, only in consortium with Desmonostoc (UFLA 12). We conclude that the inoculation of Desmonostoc (UFLA 12) and Cronbergia (UFLA 35) favours the clonal growth of S. auriculata contributing to its more vigorous spread. The fact that Desmonostoc (UFLA 12) and Cronbergia (UFLA 35) favoured the clonal growth of S. auriculata may serve as a tool to assist in understanding the excessive growth of these plants in aquatic environments, for acting as a potential biofertiliser.
